Comparative evaluation of oculokinetic perimetry and conventional perimetry in glaucoma. [PDF]

open access: bronzeBritish Journal of Ophthalmology, 1988
Oculokinetic perimetry is a new method of visual field assessment in which the patient moves the eye around a central static target to look sequentially at an array of numbers. When fixation on a number is accompanied by disappearance of the central target, that number is deleted from a recording chart.

Patients Prefer a Virtual Reality Approach Over a Similarly Performing Screen-Based Approach for Continuous Oculomotor-Based Screening of Glaucomatous and Neuro-Ophthalmological Visual Field Defects

open access: yesFrontiers in Neuroscience, 2021
Standard automated perimetry (SAP) is the gold standard for evaluating the presence of visual field defects (VFDs). Nevertheless, it has requirements such as prolonged attention, stable fixation, and a need for a motor response that limit application in ...

Retinal Nerve Fibre Layer and Ganglion Cell Complex Measurement and their Correlation with Visual Field Changes among Glaucoma Patients [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2022
Introduction: Glaucoma is an optic neuropathy that causes loss of Retinal Ganglion Cell (RGC) and changes in the visual field. The loss in RGC is determined by Optical Coherence Tomography (OCT), and visual field defects are evaluated with perimetry.

Short-Listing the Program Choice for Perimetry in Neurological Conditions (PoPiN) Using Consensus Methods

open access: yesBritish and Irish Orthoptic Journal, 2019
Background: Neurological conditions frequently cause visual field loss, commonly resulting in perimetry requests for suspected or known conditions. Currently there are no national guidelines for perimetry in neurological conditions.

Gaze-contingent flicker pupil perimetry detects scotomas in patients with cerebral visual impairments or glaucoma [PDF]

open access: yes, 2018
The pupillary light reflex is weaker for stimuli presented inside as compared to outside absolute scotomas. Pupillograph perimetry could thus be an objective measure of impaired visual processing.

Study of Optimal Perimetric Testing In Children (OPTIC): Normative visual field values in children [PDF]

open access: yes, 2015
Purpose: We sought to define normative visual field (VF) values for children using common clinical test protocols for kinetic and static perimetry. Design: Prospective, observational study.

Does eye examination order for standard automated perimetry matter? [PDF]

open access: yes, 2019
PURPOSE: In spite of faster examination procedures, visual field (VF) results are potentially influenced by fatigue. We use large-scale VF data collected from clinics to test the hypothesis that perimetric fatigue effects are greater in the eye examined ...
